vein in dogs

Any of the tubular branching vessels that carry blood from the capillaries toward the heart. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the vein is

Any of the tubular branching vessels that carry blood from the capillaries toward the heart. The atlas records it as a vein at the organ scale in the dog.

Where the vein is

It sits within the cardiovascular system. Only the system is known. The position shown carries almost no spatial information.

What the vein connects to

The atlas records 97 typed relationships for it, across 5 kinds of connection. a kind of venous blood vessel.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the vein. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as venous subtree, venous vessel, venous tree organ part, vascular element, vena and venae. Searching any of those names reaches this page.
